Parturition dates in wild Eurasian lynx: evidence of a second oestrus?

Abstract

Understanding reproductive physiology of a species is important to assess their potential to respond to environmental variation and perturbation of their social system during the mating or pre-mating seasons. We report 175 parturition dates from wild Eurasian lynx (Lynx lynx) in Scandinavia. Most lynx birth dates were highly synchronised around a mean of 30th May (SD = 9 days) with 173 of the 175 births ranging from May 2nd to June 30th. We detected two very late births on July 29th and August 15th in the absence of any indication that the females had given birth and lost a litter earlier in the year. We propose that these represent evidence of a second oestrus which is highly unusual in lynx because of their unique reproductive physiology. The rarity of these late season births has implications for lynx demography and social organisation.
